In this paper, the principle of wireless power transmission technology based on resonant coupling is discussed. A simplified equivalent circuit modeling for wireless power transmission system is established. A resonator constituted by single-layer helical coils is designed and investigated. Based on experiments, the output load voltage correlated with different distance, driving frequency and disalignment...
The transcutaneous energy transmission system (TETS) through intact skin to power a totally artificial heart (TAH) has been designed and built. Due to large air gap, the coupling ability of transformer is low. This paper selects core material, geometrical parameters, and coils axial displacement to study their effects on coupling coefficient (k). By simulating with various values, transformer is optimized...
Contact-less electrical energy transmission over a large air gap becomes more and more attractive for different applications. In certain applications, the stability of detachable transformers is of vital concern to maintain the stabilization of the whole system. This paper investigates the influence of horizontal and vertical displacement of primary system as well as transmission frequency on coupling...
